One more said: “I do believe that is Karma!!Expect all racehorses are having a good laugh about your ‘primary’ safety concerns #beingputdown?”

And there was also: “@Ruby_Walsh standing by with the humane dispatch pistol... #smallmansyndrome #jockeys are disposable.”

Walsh had already been the victim of death wishes following his comments on Tuesday, with one user posting: “Ruby Walsh I hope you get your skull crushed by one of the horses you’re so heartlessly flippant about. Animals should not die for sport.”

Another wrote: “Shame more jockeys aren’t killed instead of beautiful horses!!!!!! All jockeys are complete c****!! No horse is replaceable!”

Walsh’s injury ruined his hopes of adding to his record 41 Cheltenham Festival wins and two Gold Cup triumps. He was due to ride On His Own in Friday’s blue-ribband event.

He sparked outrage among animal rights campaigners on Tuesday by responding to the death of Our Conor on the first day of the Festival by saying: “Horses are horses. You can replace a horse. It’s sad, but horses are animals, outside your back door. Humans are humans. They are inside your back door.”

He later clarified his comments, adding: “We look after horses like they’re pets. There’s a huge difference between your pet and your family. That’s the point I was making.”
